Drew,
I agree it would be nice to unitize the different kinds of Damascus along with the laminated and stub twist.
An example would be what old L.C. Smith catalogs referred to the different grades having good, fine and finest Damascus. We know that this same type of nomenclature was used by Parker and other leading gun companies, and I'm sure their Damascus grades were the same but probably with a different name.
So I have to agree that it would be nice to have a list of what they refer to and to have it universal.
